Conclusive advantage of the present invention is that strengthening rib is arranged on the part of captive joint, to be arranged to toward each other in this at least one part.Therefore, they are accommodated in the part that forms ducted body, and invisible from the outside, and the result just can make the outside of backrest, it is smooth fully also to be that the appreciiable surface forms.By this way, just can not assemble dust, and the in-to-in strengthening rib plays the effect that guarantees the backrest necessary stability too.

Another advantage is, at least one part of in the ducted body form this can be provided with perforate, slit or similar structure, wherein, if necessary, functional features or part also can be set for example to form targeting part, holding device or similar operation or motion child seat with slit or perforate and need or in inside to it favourable structure.

As can be seen from Fig. 3, back cushion 7 comprises three

parts

17,18, and they all are made of plastic.One first part 17 is configured to identical with as shown in Figure 2 overall backrest 7.Two other or second parts 18 are elongated, and when shown in the arrow among the figure, when two parts 18 are connected to first part 17 on their common edge 26, form the latter's arm 25 with first part 17.Can realize connecting in various known modes.Friction welding, gummed, filling or bolted connection all are some possible modes.

Fig. 4 shows the lateral plan of a backrest 7.One in first part 17 of H shape and the two other parts 18 is connected to each other regularly.Select the structure of

part

17,18 to be for example half shell spare, so that the part 19 of backrest 7 forms a ducted body at least.Strengthening rib 21 is arranged in this part 19, and is arranged to toward each other in this part 19.Because strengthening rib 21 is arranged on the inboard, so be smooth at the outside face 20 of the

part

17,18 of convenient and useful part.Advantageously on first part 17, provide, and this at least one second portion 18 is only designed a stable function such as support lug 11, targeting part 15, perforate 16 and similar functionality part.

Those skilled in the art that are being freely fully aspect choice structure and the two or
